Simple question - maybe? For one-hour horizontal floor/ceiling assembly with type x 5/8” gyp bd on ceiling side of assembly – where miscellaneous fasteners are screwed into type x gypsum board/metal stud to attach strapping for ductwork or hanging fire suppression piping– what is needed (if anything) at these fastener locations to maintain assembly rating? And where can this info be found in IBC or other - to have as reference? Fastener type and install by associated trade. For commercial construction.

No one should get all that crazy about solid steel fasteners....If I had to, I would say if we allow electrical boxes with an 1/8" gap, we should probably allow a drywall screw with no gap....

Like garage door openers on a house garage attached to the 5/8 ceiling.

Except that ceiling isn't rated...And why is this in the "welcome" forum?

It's kind of rated. IRC doesn't require a tested assembly but specifically requires a min 5/8" type X membrane between the garage and living space.

Correct...It's a prescriptive technique to protect the living space from a garage, it is not a rating....This is like one of those ADA vs. building code/A117 things for me, I just like to keep the terminology straight...
